摘要

Abstract

The influence of solvent on the miscibility of polystyrene (PS) and poly (styrene-

-acrylonitrile) (PSAN) blends has been investigated viscometrically. The miscibility of different PS/PSAN blend (30/70

50/50 and 70/30) compositions in acetone and benzene at 20

and 40 ℃ was investigated on the basis of the sign of Chee (Δ

and

)

and Sun's (

) criteria. The values of these parameters were evaluated from the analyses of reduced viscosity data of binary (solvent/polymer) and ternary (solvent/polymer1/polymer2) polymer systems. These investigations indicated partial miscibility for both the blend systems. However

PS/PSAN/acetone blend system showed somewhat higher partial miscibility than the PS/PSAN/Benzene blend system highlighting the impact of solvent over the polymer-polymer interactions and hence their miscibility. The results obtained through viscometry were also corroborated by the refractive index and density results for the blends under study. The effect of temperature on miscibility in both the cases was almost negligible.
